IMPROVEMENT IN METALLIC SHUTTERS.

Specification forming part of Letters Patent No. 173,7SQ, dated'February 22, 1876; application filed October 14, 1875.

CASE A.

To whom it may concern I Be it known that I, GEORGE HAYES, of N o. in the city, county, and State of New York, have invented a new and useful Improvement in Panels for Window- Blinds, shutters, doors, screens, shades of.railroad-cars, the inclosing of verandas, summerhouses, or any structure to which movable or stationary slats are applied; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawing, which forms part of this specification.

This improvement is applicable'to indoor and outdoor purposes, on buildings or structures of various kinds, including railroad-cars and ships; and in every instance where movable or stationary slats are now used this improvement has all the advantages, with none of the disadvantages, of wooden slats, that of not entirely shutting out light and ventilation, sun, and to keep insects out of the building, and of having no movable parts, which so freqliently get out of repair, while the same or greater advantages are secured as regards the cost and effect as are claimed for the blinds, shutters, &c., in my former application for patent made on the 11th of June, 1875. This device is intended to obstruct more fully the direct rays of the sun, and to shed the Water during rain-storms, while sufficiently transmitting the indirect rays. 7

My improvement consists in perforating a metal plate in bands alternately-that is to say, I take the plate, and, instead of perforating the whole surface, I perforate it in bands Referring to the accompanying drawing,

Figure 1 represents a front view of a panel. Fig. 2 represents a vertical section of same, showing the panel in one piece.

Similar letters of reference indicate corresponding parts.

A represents the frame to which. the panels are attached B, the perforated bands; 0, the blank portions between the pert What is here claimed, and desired to be secured by Letters Patent, is

A metallic plate or panel in one piece, perforated in bands and corrugated or stepped in the manner described, and for the purpose herein set forth. I
